Here is an* update *for everyone, after a long night of work on OpenShot:

   - I have fixed the setup.py *packaging conflict* with openshot-docs.  The
   daily PPA will now install openshot (and openshot-docs) correctly.
   - I have added back in support for the *"melt" executable*, as a fallback
   option if the newer, MLT API fails to work.  This is for compatibility with
   older versions of MLT.  Seems to work great... even though it's a bit ugly.
   =)
   - I have cleaned up the *1.4.0 milestone* in LaunchPad, and moved all the
   remaining bugs into a new 1.4.1 milestone.
   - I will be posting a new blog entry regarding 1.4.0, translations, and
   other OpenShot-related news very soon.  It will probably be some time
   tomorrow, after I've tested the Daily PPA on the 4 most recent versions of
   Ubuntu.
   - We are targeting *September 23, 2011* for our release.  We need lots of
   help testing to meet that deadline.

So... in other words, the daily PPA is now working, and
MLT compatibility issues have been resolved.  Everyone should be able to
install one of these versions of Ubuntu in VirtualBox (Lucid, Maverick,
Natty, Oneiric) and then install our new *Daily
PPA*<https://code.launchpad.net/~openshot.developers/+archive/daily>.
Please let Andy or Me know if you see any big issues, or if we've missed any
obvious patches.

Thanks!
-Jonathan
